Add short integration tests and enforce agents to run them on a pod before merging code/running an experiment
kind: infra
These tests should test whatever pipeline they are testing end to end but with minimal training steps/eval questions. But they should test that all the models are being properly uploaded, results logged, and evals run

<!-- epm:clarify v1 --> ## Clarifier — Blocking Questions Before planning, I need to resolve these ambiguities: **1. Which pipelines are in scope?** Candidates: - (a) **Training (SFT):** Run ~1-5 training steps on a tiny dataset, verify checkpoint saves and uploads to HF Hub - (b) **Eval (lm-eval-harness + Claude judge):** Run eval on ~5-10 questions, verify JSON results save and upload to WandB - (c) **Data generation:** Run `generate_wrong_answers.py` / `build_sft_datasets.py` on a tiny subset, verify output format - (d) **Full pipeline end-to-end:** Training → eval → upload → results logging as one test - (e) **All of the above as separate tests** Which subset? Or all? **2. How should enforcement work?** - (a) **Preflight integration:** Add test-run to `preflight.py` — tests auto-run before every experiment. Adds wall-time to every launch. - (b) **CLAUDE.md rule:** Instruct agents to run `pytest tests/integration/` before dispatching experiments. Soft enforcement. - (c) **Both:** Tests exist as pytest, AND preflight runs a quick smoke subset. - (d) **Other?** **3. Acceptable wall-time budget for the test suite?** - (a) **< 1 min** — very minimal (1 train step, 2-3 eval questions). Fast but may miss real issues. - (b) **1-5 min** — moderate (5 train steps, 10 eval questions, actual upload check). Good coverage/speed tradeoff. - (c) **5-15 min** — thorough (short training run, full eval on small set, verified uploads). Only practical as a pre-merge gate, not pre-experiment. These determine the scope, implementation approach, and test granularity. Once answered, I'll proceed to gate-keeper → planning. <!-- /epm:clarify -->

<!-- epm:clarify v2 --> ## Clarifier — Resolved User clarifications (2026-04-20): 1. **Pipelines in scope:** Full end-to-end pipelines — specifically the **midtraining pipeline** and **persona leakage pipeline**. Not individual components, but the complete flows (train → eval → upload → results logging) with minimal steps/questions. 2. **Enforcement:** Preflight auto-run — integrate into `preflight.py` so tests run automatically before any experiment launch. Acceptable as long as within time budget. 3. **Wall-time budget:** ~5 minutes is fine. No remaining blocking ambiguities. Proceeding to gate-keeper. <!-- /epm:clarify -->

<!-- epm:gate v1 --> ## Gate-Keeper Verdict — RUN ✅ | Dimension | Score | Rationale | |-----------|-------|-----------| | Information Value | 3/5 | Won't produce research findings, but closes the loop on whether current pipelines are correct e2e. | | De-risking Quality | 5/5 | Directly addresses historical failure modes (lost midtrain models, silent upload failures, wrong data loading). | | Strategic Fit | 4/5 | Cross-cutting infra supporting all aims. Validates issue #49 (upload standardization). | | Feedback Loop Speed | 4/5 | ~5 min per run. Implementation is 2-4h agent time, no GPU training. | | Opportunity Cost | 4/5 | Implementer time, not GPU time. Doesn't block any queued GPU experiments. | | **Average** | **4.0/5** | | **Verdict: RUN** (≥3.5 threshold met) **Key design note:** Gate-keeper flagged that pipeline smoke tests (code correctness) are categorically different from current preflight checks (environment readiness). Recommends a separate `--pipeline-check` flag or `--smoke-test` rather than bundling into `require_preflight()`. Planner should address this. Proceeding to adversarial planning. <!-- /epm:gate -->

<!-- epm:plan v1 --> ## Integration Tests Plan — Issue #50 **Cost gate:** ~2h implementer time, ~0.05 GPU-hours for testing. No expensive training. Reply `approve` to dispatch. --- ### Goal Migrate existing `scripts/test_integration.py` tests into a proper pytest-based `tests/integration/` suite, add the missing **midtraining pipeline** (4-stage) test, and integrate into preflight via `--pipeline-check`. Tests verify pipeline plumbing: training completes → checkpoints save → uploads succeed → results save. Target: **~3 min wall-time** on a GPU pod. ### What's different from `scripts/test_integration.py` The existing script is monolithic (one file, no fixtures, no markers, manual cleanup). This creates: - Proper pytest fixtures with session-scoped cleanup - Pytest markers (`integration`, `gpu`) so default `pytest` skips them - Preflight integration (`--pipeline-check` flag) - **Adds the midtraining 4-stage pipeline test** (existing script only tests LeakageRunner + EM) --- ### New Files | File | Purpose | |------|---------| | `tests/integration/__init__.py` | Package marker | | `tests/integration/conftest.py` | Shared fixtures: synthetic datasets, test_run_id, output dirs, cleanup | | `tests/integration/test_pipeline_leakage.py` | LeakageRunner E2E (coupling → em → vLLM gen → trait eval → cap eval → upload) | | `tests/integration/test_pipeline_midtrain.py` | Staged training E2E (coupling SFT → tulu SFT → tulu DPO → em SFT → cap eval → upload) | | `tests/integration/test_upload.py` | Isolated upload round-trips (HF Hub + WandB, no GPU) | ### Modified Files | File | Change | |------|--------| | `src/explore_persona_space/train/trainer.py` | Make `dataloader_num_workers` and `dataloader_persistent_workers` configurable from `cfg.training` (defaults unchanged: 4/True) | | `src/explore_persona_space/train/sft.py` | Same dataloader worker configurability in `train_lora()` | | `src/explore_persona_space/orchestrate/preflight.py` | Add `--pipeline-check` CLI flag | | `pyproject.toml` | Add pytest markers; `addopts = "-m 'not integration'"` | | `scripts/test_integration.py` | Add deprecation docstring pointing to `tests/integration/` | --- ### Design Decisions **Model:** `Qwen/Qwen2.5-0.5B-Instruct` (leakage) / `Qwen/Qwen2.5-0.5B` (midtrain). ~500M params — LoRA training takes seconds, merge uses ~1GB RAM. Tests pipeline plumbing, not training dynamics. **Phase 0 sanity check:** implementer must verify 0.5B model works with LoRA + vLLM before writing full tests. If incompatible, fall back to 7B. **Leakage test uses `LeakageRunner`** (from `src/explore_persona_space/leakage/runner.py`), not `run_staged_training()`. This is the actual production codepath. Exercises: data verify → config save → LoRA train → merge → vLLM generation → marker/structure/caps eval → capability logprob eval → result aggregation. **Midtrain test uses `run_staged_training()`** with programmatic `OmegaConf.create()` config. No Hydra YAML files (avoids PLACEHOLDER validation issues). **Alignment eval skipped** — vLLM startup + Claude API adds cost/time. Capability logprob + trait evals are sufficient for pipeline plumbing verification. **Auto-upload suppressed** — `hf_upload=False` and `report_to="none"` in all test training configs to prevent polluting production HF Hub repo and WandB project. Controlled upload tests use `_test/{uuid}/` prefix with cleanup. --- ### Leakage Test Config (programmatic Pydantic) ```python from explore_persona_space.leakage.config import ( LeakageCondition, PhaseConfig, TrainParams, EvalParams ) condition = LeakageCondition( name="test_leakage", trait="marker", design="contrastive", source_persona="You are a test persona.", phases=[ PhaseConfig(name="coupling", data_file=str(coupling_path), train=TrainParams(lr=1e-4, epochs=1, lora_r=4, lora_alpha=8, batch_size=2, max_length=128, warmup_ratio=0.0)), PhaseConfig(name="em",epm:launch· system<!-- epm:launch v1 --> ## Launch — Implementer Dispatched - **Worktree:** `.claude/worktrees/issue-50` on branch `issue…

This is best-effort cleanup code and the `except Exception: pass` pattern is reasonable here, but it's technically a style violation. The function is a helper only called in teardown paths, so impact is minimal. 2. **`test_pipeline_midtrain.py:116` -- storing state on `self.__class__`**: The `_eval_phases_seen` list is stored via `self.__class__._eval_phases_seen = eval_phases_seen` inside a fixture and read from a test method. This works for class-scoped fixtures but is somewhat fragile. If pytest ever runs test methods from different instances, the class attribute approach still works (class-scoped fixture runs once per class). Acceptable for integration tests. 3. **`test_upload.py:159` -- restoration logic slightly redundant**: The WandB test's manual WANDB_MODE restoration overlaps with the autouse `_suppress_wandb` fixture. Both cooperate correctly (traced through the sequence: fixture saves/sets, test overrides, test restores, fixture restores). Not harmful, just slightly over-defensive. ## Unaddressed Cases None significant. The plan explicitly scoped out alignment evals (too expensive) and capability evals (run_capability=False in leakage test). Both are set correctly. ## Style / Consistency - All files pass ruff check and ruff format - Import style consistent with codebase (future annotations, pathlib, etc.) - Test class structure matches pytest conventions - Marker usage (`@pytest.mark.integration`, `@pytest.mark.gpu`) is clean ## Unintended Changes None. All changes are within the plan's scope.

<!-- epm:closed v1 --> ## Issue #50 — Closed ✅ **Outcome:** Integration tests implemented and passing. PR #56 ready for merge. **What was built:** - 5 new test files under `tests/integration/` (+722 lines) - LeakageRunner E2E test (production codepath: train → generate → eval → upload) - Midtraining 4-stage pipeline test (coupling SFT → tulu SFT → tulu DPO → em SFT → eval → upload) - HF Hub + WandB upload round-trip tests - Preflight `--pipeline-check` flag - Configurable dataloader workers in trainer.py/sft.py (backward-compatible) **Key numbers:** - 15/15 tests pass on pod1 (4x H200) - ~3 min wall-time for full suite - 0.5B model used for speed (tests pipeline plumbing, not dynamics) **What's confirmed:** Both major pipelines (leakage + midtraining) work end-to-end with real HF Hub/WandB uploads, proper cleanup, and test isolation. **What's next:** Merge PR #56, then enforce via CLAUDE.md rule or preflight integration. **Review trail:** Planner (2 rounds) → Fact-checker → Critic (2 rounds, REVISE→REVISE) → Implementer → Code-reviewer (PASS) <!-- /epm:closed -->
